Today, Mozilla released the fourth beta of Firefox 4.0. After a period of what I would call stagnation, the Mozilla team are back on track with delivering interesting UI concepts. They were sensible enough to copy Chrome's excellent tabs-on-top UI, but have now also added something called Panorama, a new and very interesting way of managing your open tabs.

Due to this article, I just went and download the Firefox 4.4 beta and gave Panorama a spin.

It's actually pretty cool. Yes, I could live without it, and maybe I won't even use it much. Still, it's not a bad concept, and I'm not sure why some people here are complaining about it. Now if it hurts performance, then yes, I'd be against it. So far, I haven't noticed a speed difference, but I've only been using it for about 5 minutes. I'll be keeping my eyes open to see how well it performs.

Thanks Thom for this article. I might not even have noticed Panorama for months if you hadn't pointed it out.
